Gmail add new feature to simplify the process of unsubscribing newsletter or mailing list from within Gmail. By now, after you click on ’show details’, you’ll notice new ‘unsubscribe from this sender’ link available.

According to the Gmail blog post, clicking the link will automatically send a request back to the sender so they’ll stop emailing you.

This unsubsribe option is not visible for email from suspected spammers (after all they’re spammers right??)

Gmail said this is not working for all senders at the moment. In my observation of emails that have the unsubscribe link and those that not.

Email from sender with Gmail unsubscribe links

• Google Alerts
• Subscibed comments

Email from senders without the Gmail unsubscribe links

• RSS subsribed post
• Getrepond
• Aweber
